Description

Cyclohexanecarbonyl Chloride, 1-(2-Propynyl)- (9Ci) is a specialized organic building block featuring a reactive acid chloride group and a propargyl (2-propynyl) substituent on the cyclohexane ring. This unique bifunctional structure makes it a critical intermediate for synthesizing complex molecules in advanced research and development. It is primarily needed by pharmaceutical, agrochemical, and advanced material industries for creating novel compounds through targeted acylation and click chemistry reactions.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates, particularly those requiring cyclohexyl or propargyl motifs.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, and fungicides.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for creating specialty polymers, resins, and functional materials.
• Click Chemistry Reagent: The propargyl group enables efficient Huisgen cycloaddition (click) reactions for bioconjugation and material surface modification.
• Organic Synthesis Research: A versatile reagent in academic and industrial R&D labs for constructing complex organic frameworks via acyl chloride chemistry.
• Ligand & Catalyst Development: Used to synthesize novel ligands for metal complexes and organocatalysts.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and ensure maximum shelf life.
